AbstractThe overall goals of this research were to: (a) examine whether help‐seeking intentions, subjective needs, depressive symptoms, and social support can predict actual help‐seeking behavior; and (b) clarify the moderating effects of social support on help‐seeking behavior using a longitudinal design. University students (N = 370) completed questionnaires that measured social support, subjective needs, depressive symptoms, and help‐seeking intentions during Time1, and questionnaires that measured actual help‐seeking behavior during Time2. Only subjective needs showed a positive effect on both help‐seeking intentions and actual help‐seeking behavior. Although depressive symptoms had a negative effect on help‐seeking intentions, they had a positive effect on actual help‐seeking behavior. Moreover, social support had a positive effect on help‐seeking intentions, and moderated the influence of subjective needs on actual help‐seeking behavior. Simple slope analysis indicated that subjective needs did not facilitate help‐seeking behavior among those with low levels of social support.
